How do wool like hairs benefit some cactus plants?

Wool-like hairs on cactus plants, known as trichomes, provide several benefits. They help reduce water loss by creating a microclimate that traps moisture and lowers the temperature around the plant's surface. These hairs also offer protection from intense sunlight and serve as a barrier against herbivores and pests. Additionally, they can aid in capturing and condensing moisture from the air, further supporting the cactus's survival in arid environments.
